OpenLIT is an open-source LLM and GPU observability tool built on OpenTelemetry. It offers tracing, metrics, and a playground to debug and improve LLM apps. Supports 20+ integrations like OpenAI, LangChain, and exports data to your existing observability tools
Hi Product Hunt!
I'm Aman, the founder and maintainer of OpenLIT. Today, we're thrilled to introduce OpenLIT, the first truly open-source observability and analytics platform based on OpenTelemetry, designed to monitor the entire LLM Stack—from the LLM applications themselves down to the GPU infrastructure layer—with just one line of code.
Building an MVP with LLMs is fast, but turning it into a polished product is hard. In our previous projects, we've spent countless hours dealing with common challenges that many LLM engineers face. Probabilistic outputs can be inaccurate or costly. High inference costs eat into budgets. Applications often suffer from high latency due to long response times from LLMs. Debugging complex LLM setups like chains, agents, and tools, is toughhhh. Plus, understanding user behavior from open-ended prompts and interactions is difficult.
We've faced these challenges too and that's why we created OpenLIT—to support developers by providing crucial insights into production data to enhance LLM application performance (without sweating).
Key Features:
⚡ Comprehensive Logging: Log full queries, errors, and metrics for every request.
🔍 Inspect & Debug: Visual UI to track token counts, compute costs, and latency over time.
👨👩👧👦 User Tracking: Monitor user interactions and gather feedback effectively.
🕹️ Prompt Playground: Test and optimize different prompts and LLMs.
🐾 Detailed Traces: Debug complex agent interactions easily.
🧪 Output Evaluations: Ensure high-quality, accurate responses.
💯 Seamless Integration: Export data to your existing observability stack without hassle.
